基于GIS的综合地层柱状图成图技术研究与实现

Research and Realization of the Synthetic Stratum Histogram in Regional Mapping Technology Based on GIS

在对新疆塔城盆地基础地质资料收集和分析的基础上,结合GIS技术,建立了塔城盆地综合地层剖面的空间数据库,并设计出自动绘制通用的综合地层柱状图制图模块,完成了综合地层柱状图表格的自动绘制,文字信息的录入及自动化标注,以及岩性符号的制作、绘制及管理,并实现了岩性符号库建立,最后将符号库中的每个岩性符号进行编码,通过岩性符号柱状图属性码与相应的岩性符号编码的匹配自动实现所有岩性柱状图的符号化表达。该技术的实现,是对传统综合地层柱状图绘制的一种改进。

Based on the collection and analysis of the basic geological data of Xingjiang Tacheng Basin and on the GIS technology, a synthetic stratum section database for Tacheng Basin was established and a synthetic stratum historgram drawing model was designed and used to complete the automatic drawing of the relevant form, the labeling of writing information and the making, mapping and managing of lithological symbols. The lithological symbol database was established and each symbol coded, realizing the automatic symbolized expression of all lithological historgrams by matching the attribute codes of historgrams with those of corresponding lithological symbols. The technology is an improvement of the conventional drawing of synthetic stratum historgram.
